Earlier on Thursday, two Afghan police officers were killed in a terrorist attack in the north-western province of Badghis, while another seven people, including three police officers, were injured.

Over the past week, the Taliban militants have staged a series of massive terrorist attacks in Afghanistan.

On Sunday, 57 people were killed and over 60 others were injured when a suicide blast ripped through crowds at a volleyball match in the south-eastern province of Paktika, in the country's deadliest terrorist attack this year.

In a separate incident, two NATO servicemen were killed in an attack in Kabul on Monday.
